CURTAIN-FASTENER.

Specification of Letters Patent.

Patented Apr. 21., 1914.

Application filed August 19, 1911. Serial No. 645,045.

To all whom it may concern:

Be it known that I, Josnvrr HAAs, Jr., a citizen of the United States,and a resident of the city of Newport, in the county of Campbell andState of Kentucky, have invented certain new and useful Improvements inCurtain-Fasteners, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification. 1

My invention relates to curtain fasteners for securing curtains and thelike to frame work, and more particularly for use for curtains onvehicles, especially for automobiles, where the curtains are subjectedto heavy and violent wind pressure and the fasteners are under almostcontinuous jarring and jolting strains.

The object of my invention is to provide a curtain fastener of the turnbutton kind, which shall be strong and durable, and at the same timelight and attractive in appearance, and easily operated to release orlock the curtain in position and with which the liability of jarringloose under jolting strains and varying wind pressure will be reduced toa minimum.

The several features of my invention and the various advantagesresulting from their use conjointly or otherwise will be apparent fromthe following description and claims.

In the drawings, Figure 1 is a top plan view of my improved curtainfastener. Fig. 2 is a central transverse section of the same. Fig. 3 isa side elevation of the button stud. Fig. 4 is a plan view of therotatable locking disk. Fig. 5 is a side elevation of the same. Fig. 6is a plan view of the bottom plate, and Figs. 7 and 8 are plan and sideelevations of the top plates, between which plates the locking disk ismounted. Fig. 9 is a plan view of the clenching plate employed as a basefor the attachment of the fastener to the curtain material.

A portion of the frame to which the curtain is to be fastened isrepresented by 1, and the curtain material by 2. At each point at whichthe curtain is to be fastened, a post or stud 3 is permanently fixed orsecured in any suitable way. In the construction of stud illustrated, 41is the base of the stud, provided with a depending stem 5 for securingthe stud in position. The head of l the stud 6 is provided with lateralextensions '7, 7, formed by undercutting the head portion with a groove8, and in the preferred construction the head is oblong in shape.

Secured to the curtain material 2, at the 2 proper points for fasteningto the studs, are the turn button fasteners.

The turn button comprises a disk 9, preferably of resilient sheet metal,provided with an openfing 10, corresponding in size andshape to thehead6 of the stud, so as to allow for the passage of the head when thedisk is in with a suitable finger hold 11, extending upwardly from theplate to be readily grasped, and in the present instance this fingerhold comprises a semi-circular loop of wire secured at its ends to thedisk. The disk 9 is mounted on a bottom plate 12, provided with asimilar opening 13 to that in the locking disk, and the locking disk isheld in place by the annular top plate 14, which is provided with tangs15, 15, to pass down through slots 16, 16, in the bottom plate andthrough the curtain material 2 and through slots 17, 17, in the annularclenching plate 18, which is placed on the under surface of the curtainmaterial, and over which the tangs 15 are clenched to secure thefastener to the curtain material.

The locking disk 9 is bent slightly transversely as illustrated in Fig.5, so as to give resiliency to the disk, and lugs 19,19, are formed onthe under surface of the locking disk by depressing the material atthese points, while the bottom plate 12 is provided with correspondingdepressions 20 arranged ninety degrees apart, in line with the major andminor axes of the oval opening 13, so that in either of the twopositions of the locking disk the spring of the plate will cause thelugs to engage in the depressions and lock the disk in open or closedposition. The use of the curtain fastener will be evident from theforegoing description. To secure the curtain, the locking plate 9 isturned so that the oval opening 10 will be parallel with the head of thestud; the head of the stud is then passed through the oval opening andthe locking plate given a quarter of a turn by the finger hold 11, thusbringing the edges of the plate under the undercut portion of the headof the stud. The resiliency of the plate causes the lugs 19 to engage inthe depressions in the bottom plate in either of these two positions tosnap in place when the plate is turned, thus locking the plate againstany movement under the jars and jolts of the vehicle.

The construction is light and attractive in appearance, is formed of aminimum number of parts, is readily and easily manufactured and can befastened to the curtain material by merely clenching the tangs 15 overthe clenching plate 18.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. In a curtain fastener, the combination with a fixed button studhaving a laterally extending head and adapted to be secured to theframe, of a turn button fastener adapted to be secured to the curtain,comprising an upper and a lower fixed plate with a rotatable platemounted between the fixed plates, the rotatable plate provided with anopening to allow the passage of the head of the stud when in oneposition, and to lock under the head of the stud in another position,the rotatable plate formed of resilient sheet metal bent transversely tomaintain a spring pressure between the upper and lower fixed plates, andprovided with raised portions to engage correspondingly depressedportions in the fixed plate to lock the rotatable plate in open andclosed positions.

2. In a curtain fastener, the combination with a fixed button stud andadapted to be secured to the frame having a laterally extending head, ofa turn button fastener adapted to be secured to the curtain, comprisingan upper and a lower fixed plate with a spring plate rotatably mountedbetween the two fixed plates, said spring plate having an opening toallow the passage of the head of the stud in one position and to lockthereunder in another position, with a finger hold comprising asemi-circular loop extending upwardly from the rotatable plate to rotatethe same, the rotatable plate and one of the fixed plates havingcorrespondingly raised and depressed portions to lock the rotatableplate in open and closed positions with said rotatable plate benttransversely to maintain spring pressure between the rotatable plate andthe fixed plate.
